It's an interesting idea, but I don't think the time is right just yet for basic income. When AI is to the point that most skilled jobs can be automated and humans don't really need to work, then we can start giving people money.
YC is taking the long term view, which is great.
But what concerns me is the way in which Basic Income is already getting heavily politicised.
Politicians are already using it to attract voters (front page of UK Guardian today, Labour party are "considering" a basic income).
We are still very much at the research stage.
